Col Vert

Between the Roc Cornafion (2049 m) to the north and the Gerbier ridges (2019 m) in the south, the Col Vert is a breach at 1766 m of altitude allowing to join the Trièves. Formerly, this passage was taken by the Trièvois who would buy in the spring and autumn their cows of the city race at the fairs of Quatre Montagnes, while Du Trièves, Claix and Varces rose from the brandy and wine for the inhabitants of the Vercors. The ruin resting on the rock of the Vert Pass testifies to a place of arrest for these exchanges.
